ADJUSTABLE DRAW-BAR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 248,291, dated October18, 1881,- Application filed July 29, 1881. (No model.)

To all whom it may concern Be it known that we, BENJAMIN F. CLARK and.CHARLES OORNWELL, citizens of the United States, residing atPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in AdjustableDraw-Bars for Street-Railway Cars; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,reference being had to the accompanying drawings, which form part ofthis specification, in which-- Figure 1 is aplanofa portion of the truckof a street-car, partly broken away, illustrating our improvements asapplied thereto. Fig. 2 is an inverted plan thereof; Fig. 3, alongitudinal vertical section; Fig. 4, a transverse vertical sectionthrough platform-openings; and Fig. 5 is a perspective of a detailmodification.

' Our improvements have for their object to provide means wherebystreet-cars may be drawn over openings in the streets between the trackswithout disconnecting the horses from such cars.

Our invention consists, essentially, in the provision of a draft-bar,which may, as occasion requires, be swung to either side of the car,thus allowing the horses to draw the car over an opening between thetracks, the horses walking outside the track without being detached fromthe car and the tongue not being uncoupled.

At present when an opening is made in the streets for laying gas orwater pipes, or for other purposes, and where such opening crosses thetrack of a street-railway, or is made between them, it is the practice,in order to get a street-car over such opening, to detach the horses andcar and tongue, push the car along the tracks, walk the horses to oneside of the same, and reconnect them and the ton gue with the car afterthe opening has thus been passed. This consumes much valuable time, andis a source of considerable annoyance and inconvenience to drivers andpassengers; To avoid this we construct thedraw bar (hitherto made rigidand laterally immovable) in such manner that without detaching thetongue or pole therefrom, and without disconnecting the horses from thelatter, said draw-bar may be swung obliquely to one side or the other ofthe car,

thus permitting the horses to walk'outside the tracks and pull the carover an opening between said tracks.

Our invention accordingly consists, first, in the combination, with astreet-car, of a laterally-adjuslable draw-bar, or one which can beswung obliquely to one or either side of the car; and, secondly, incertain details of construction and combination, as hereinafter fullyset forth. I

Referring to the accompanying drawings, A indicates the bodyot' astreet-carsupported on wheels B B, running on tracks 0 0, between whichis shown, at w, an opening which it is desired to cross withoutdetaching the horses from the cars or unco pling the tongue or pole,(shown at D.)

E represents the draw-bar, which is slotted longitudinally at c, inwhich slot is a roller, f, whose spindle F is made fast to the body orsills of the car.

Gr shows a crank whose center g is made fast to the sills or bottom ofthe car, its winch g being fastened by a bolt, 9 to the end of thedraw-bar E.

H represents a yoke which passes laterally under the drawbar, its endsbeing secured at h h to the car-sills.

e is a roller sustained on the drawbar E so as to roll against a bowedbar, I, fastened to thecar-sills at t t.

K K are linchpins or king-bolts, which pass down through openings k inthe front platform of the car. One of these openings, 7c, is directly inthe middle of the platform and registers with a center hole, e in thedraftbar. The other openings, It k, are on either side of the opening70, so that a pin or bolt passing through either of them willjust clearthe draw-bar or pass down to one side of it.

k k are other openings in or about the front corners of the platforms,and designed for the reception of one of the bolts K K when the draw-baris swung around to either side.

The operation is'follows Normally the parts are arranged as in Figs. 1and 2, the draw-bar driven to a position to one side of the track. Thetongue or pole not being uncoupled from the draw-bar,this causes thelatter to be moved obliquely, the roller 0 moving against the bowed barI until it reaches one of the straight ends of said bar, and the crank Gswinging around to the other side, the parts occupying the positionshown in dotted lines in Fig. 1. One of the pins K K is now passed downthrough the corner openings, k or it and inside of the drawbar. Thehorses are now driven straight ahead, walking by the side of the track,drawing the car across the opening. After crossing the latter the pin Kis withdrawn from openings k or k, reinserted in either one of openings70, the horses moved over to the middle of the track, restoring thedraw-bar to its central position, the pin K is restored to the centralopening, and the car started on its journey. All this can be done by thedriver withontleaving the platform, and in less time than it takes todescribe it. The object of using two pins is that one may serve as astop in moving the draw-bar back to its normal position, and thusprevent said bar from going past the center.

Instead of having the yoke H and bow-bar I separate, as shown in Figs. 2and 3, they may be made in one piece; or the bow-bar may be slotted atz" for the passage of the draw-bar, as shown in Fig. 5. Said draw-barmay be straight from its inner end to the pole-socket E or it may have agoose-neck, 6 to enable it to pass the brake-bar without contact withthe latter.

The crank Gr serves asa check and guide for the inner end of thedraw-bar, preventing it from moving too far backwardly or too much toone side in swinging round.

In lieu of a crank a platform with a guideslot, into which a pin orroller on the inner end of the draw-bar fits and in which it moves, maybe employed, said platform being rigidly secured to the under side ofthe car-sills. This we mention as the equivalent of the crank, and asincluded in our invention and claims.

What we claim as our invention is as follows:

1. In combination with a street-car, a laterally-movable draw-bar, andmeans, substantially as specified, for holding the same firmly in placewhen moved to one side, substantially as and for the purpose set forth.

2. The draw-bar E, longitudinally slotted at e, and secured to the bodyor sills of the car by a bolt or pin, F, passing through said slot,substantially as shown and described.

3. In combination with the draw-bar E, slotted at e, and provided with abolt, F, passing through said slot, the crank Gr, substantially as andfor the purpose set forth.

4. In combination with the bow-bar I, the draw-bar E and roller ecarried thereon, substantially as shown and described.

5. The bow-bar I, slotted at t, for the passage of the draw-bar,substantially as shown and described.

6. In combination with the laterally-adjustable draw-bar E, the platformA, having center openings, 70 k, and corner openings, 70 10 for thepassage of pins or bolts K K, substantially as shown and described.

7. In combination with the movable drawbar E, having opening 0 theplatform A, having middle opening, 70, and openings kon either sidethereof for the reception of stop bolts or pins K K, substantially asshown and described.

8. The combination ofa slotted drawbar, E, rollerf, crank G, bow-bar I,roller 6, platform A, having openings 70 7c k 70 and pins or bolts K K,substantially as shown and described.

In testimony that we claim the foregoing we have hereunto set our handsthis 26th day of July, 1881.
